2D Ising-Heisenberg model with quartic interaction

We propose a two-dimensional spin-1/2 Ising-Heisenberg model with quartic interaction. In this sense the phase diagram for the model at zero temperature is studied, obtaining four different configurations for the unitary cell. It should be observed that using the rotation and spin inversion symmetry...
